Abstract

The invention discloses a device for detecting physical properties of a micro-nano-scale substance. The device comprises a support frame, a high-precision positioning platform and a focusing device. The support frame is composed of an upper support plate and a lower support plate. The high-precision positioning platform is composed of a three degree-of-freedom nano-precision displacement table anda two degree-of-freedom micron-precision displacement table. The three degree-of-freedom nano-precision displacement table and the two degree-of-freedom micron-precision displacement table are orderly arranged above the support plate. The nano-precision displacement table is provided with a sample stage. The top of the upper support plate is provided with a triangular mounting plate through a connection rod. The triangular mounting plate is provided with a probe lifting motor and a probe holder. The probe holder clamps a probe. A focusing device includes a microscope tube, a focusing motor, aCCD video sensor and an objective lens. The objective lens and the CCD video sensor are mounted on the microscope tube. The microscope tube is mounted on the focusing motor. The lower support plate is equipped with a two degree-of-freedom coarse adjustment displacement table. The focusing motor is installed on the coarse adjustment displacement table.

Description

technical field [0001] The present invention relates to a kind of equipment dedicated to the physical properties of micro-nanoscale substances, in particular to a physical device for micro-nanoscale particles (such as polymer particles) and micro-nanoscale living biological materials (cells, proteins, DNA, etc.) Devices for feature detection. Background technique [0002] Cancer is currently diagnosed as the second leading cause of death in the world. In 2012, there were 14.1 million cancer patients worldwide, and it is estimated that by 2035, this number will reach 24 million. It is very urgent to improve the means of understanding the status and development of cancer task. In 2007, Subra Suresh of the Harvard-MIT Department of Health Science and Technology summarized the current status of cancer cell research and pointed out that the mechanical properties of cancer cells are significantly different from normal cells. In the past few years, single-cell biology research has...
